Abstract: 
Досліджено оптимізацію кислотного гідролізу при виробництві етанолу, перспективного альтернативного палива, з лігноцелюлозних матеріалів (бамбука). Показано, що перетворення бамбука в етанол може бути здійснено трьома етапами: попереднє оброблення деревини бамбука для видалення лігніну та геміцелюлози, кислотного гідролізу попередньо обробленого бамбука для перетворення целюлози у відновлений цукор (глюкозу) та бродіння цукру з утворенням етанолу з використанням анаеробних бактерій Saccharomyces cerevisiae. Досліджено вплив параметрів на стадії гідролізу та експериментально встановлено оптимальні параметри (температура, час та концентрація кислоти). Вплив параметрів гідролізу на вихід етанолу встановлено за допомогою 32 факторного експерименту з використанням програмного забезпечення Design-Expert® 7.
